I didn’t see the litteral interpretation of that word which is using in Greece now. I saw only the metaphorically. This use is: Α painting or icon of a face or body of a saint or saints or Christ ; as well as of a religion subject.

Interesting that you should mention this, astrokatastro, as this more literal usage has, in English, been entirely supplanted by the figurative. But «hagiography» retains its literal sense of «biography of [i e, writing about] a saint or saints», and «Hagiographa» is a (little used) term for the Bible....
